Hi Deborah,
Welcome to the Forum, I’m sure you will get lots of help here, and it’s a great place to chat with other people in the same situation.
If you go on the thread that Teresa started, there is about 5 or 6 Mums all with sons with addiction.
My Son is an addict, alcohol and cocaine, and I understand completely where you are coming from.
I think he has told you because he obviously needs help, all you can do is point him in the right direction as Kellie said, they have to want to be helped.
Take care of yourself and keep in touch on the Forum.
